You won't get better FPS, load times etc with a better power supply. But it will keep your system more stable, stop crashing etc and might get you a better overclock compared to a lesser model.

I have recently been playing around with a very old 10 amp 12v rail PSU and have installed it for the rig in my sig (just to see if it worked) and have had nothing but flawless performance given a 2700mhz OC and also the xl is OCed as-well. It has been running for maybe 2 weeks straight with plently of gaming and it is always folding. I am surprised at it being able to cope, but it can. It is turning me to maybe cheap power supplies for this rig in the future. As I will be running SLI with my new rig and a heavy OC I will not even be thinking about a cheap under-powered PSU. That would only give me hassles. Cheap equipment is cheap and might get the job done in some cases but there is no substitute for good quality.

^^I have an old 300W Fortron with 8 amps on the 12v rail that powered my older system (Celly 2.5 @ 2.9, 768mb RAM, MX400, 2 hard drives, 2 optical drives, sound card and network card) flawlessly. I loved that little thing, but it couldn't quite handle powering my 6600GT.

I still have a 235W Fortron in my DOS machine. No idea how many amps are on the 12V rail, haven't looked. But it powers a P166 @ 200MHz and a Diamond S3 pretty well. My sister's PIII 500 and Radeon 7000 are powered by a 235W Sparkle.

The psu is probably the most overlooked but important piece of hardware you can buy..Every system starts at the psu and the system built around it ..I would reccomend a good quality psu

I just could't go cheap on such an important part of the system, so I got a PC Power and Cooling since it is a "true" 510 W power supply. Alot of the cheap power supplies are only rated under ideal temperature conditions. I'm sure there are good power supplies for less, but research and see what others have success with before buying the bargain PSU.
